The team of researchers has found a way to make the terahertz band of the electromagnetic spectrum — the spectrum band between microwaves and infrared light — usable for medical or consumer devices. As infrared light can be viewed by some night vision goggles, devices that can image the terahertz band could see through drywall, wood, even human skin. This band has been used before, but the new solution is cheaper and simpler to create.
